Module Insertion Tool With Segmented Support Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for inserting microcircuit modules into housings face challenges in distributing pressing force effectively, leading to risks of dust trapping and module deformation, as they either trap dust or apply excessive pressure.
Innovation Solution
A tool with a support surface shaped to fit the module's footprint, featuring a circular outer contour and anti-static treatment, which circumscribes the suction cup to minimize dust trapping and evenly distribute force, while preventing rotation and ensuring the module's corners remain free from pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If the bearing surface merges with the module surface to present the largest possible contact surface, then the pressing force is well distributed and low pressure is obtained, but dust is trapped between the bearing surface and module surface leading to detrimental marks
Solution Approach 1:
The bearing surface is segmented into multiple discrete support points (studs) rather than a continuous surface. This segmentation reduces the total contact area to prevent dust trapping while still providing sufficient support points to distribute the pressing force adequately across the module surface.
Solution Approach 2:
The support points are strategically positioned at specific locations on the module surface where local support is needed. This allows the pressing force to be distributed to critical areas while leaving other areas (particularly corners and edges) free from contact, preventing both dust trapping and module deformation.
2Object-affected harmful factors
If the support surface is reduced to a few isolated studs, then the risk of dust trapping is reduced, but greater pressure is applied leading to detrimental deformation of the module
Solution Approach 1:
The bearing surface is divided into multiple discrete support points distributed across the module surface. This segmentation allows the total pressing force to be divided into smaller forces at each contact point, reducing the pressure at any single location and preventing module deformation while still providing adequate support.
Solution Approach 2:
Multiple support points are combined to work together as a distributed support system. The collective effect of multiple low-pressure contact points provides sufficient overall support to prevent module deformation during insertion, while each individual contact point maintains low enough pressure to avoid localized damage.
3Stress or pressure
If a continuous bearing surface is used to distribute force evenly, then low pressure is achieved, but the surface area increases the risk of dust trapping
Solution Approach 1:
The continuous bearing surface is segmented into discrete support points, dramatically reducing the total contact area. This segmentation maintains force distribution benefits while eliminating the large continuous surface that traps dust, as the gaps between support points allow dust to pass through or be excluded.
Solution Approach 2:
Support is provided at specific local positions rather than across the entire surface. The support points are positioned to provide force distribution where needed while leaving the majority of the surface area free, thus achieving pressure uniformity at critical locations without the dust-trapping penalty of a large continuous bearing surface.

AI summary
The tool has a push rod (4) and a circular suction cup (5) placed at an end of the push rod to selectively maintain a module (3). A support unit (41) is placed at the same end of the push rod so as to be supported on the module. A bearing surface (42) of the support unit contacts with the module to leave corners of the module to be free. The module includes a flat surface, and the bearing surface is formed to be inscribed in a cavity of the module. The bearing surface is limited by a circular contour.
